best way to apply poly release film to mould

My mould mainly consists of flat vertical sections. To aid release of my item i am trying to use some poly release film as its hard for me to get a chisel in and get enough leverage to pop the item out of the mould. What is the best way to secure the film to the mould? is it best to use a spray adhesive if so what is best?

HI, Unfortunately release film is not used for this purpose so we cannot recommend the best way to apply this as this is outside of the conventional methods of molding . If you wish to e-mail pictures and more info of on your project to tech@ecfibreglasssupplies.co.uk I may be able to offer more advice on the best approach. Kind rgds Martin
